About this product

Model:  iop_ipolar_3339r-sgp
Part Number:  3339R-SGP

Introductory Price - new iOptron iPolar - a high precision, easy to use electronic polarscope!

Includes adapter for iOptron SkyGuider-Pro Mounts.

The new iOptron iPolar electronic polarscope is a quick, easy way to accurately polar align your mount, even when you cannot see the pole star!

Accurate polar alignment has never been so simple, just put the 'X' on the 'Spot'! Well the 'X' does look more like a '+' and the 'Spot' isn't there but instead a representation of the celestial pole's location. Using the iPolar's graphical interface, the two overlaid symbols represent a precise polar alignment ensuring peak performance from your equatorial mount.

The iPolar utilises an electronic camera aligned with both the axes of your telescope mount. The software processes the camera images calculating the true pole's location, then guides you through adjustments needed to align your mount to the celestial pole. Gone will be the days of crouching behind a 'through the mount' polar scope, the iPolar facilitates making altitude and azimuth adjustments by just glancing at your laptops monitor. This system needs as few as four stars to locate the pole, and can do so even when the pole location itself is blocked by clouds, tree branches or other obstructions.

iPolar electronic polarscopes are available for most iOptron and other brand equatorial mounts.

Great piece of kit. Runs great with a small 10" laptop which is ideal for in-the-field alignment.
Great service from First Optical helping out with the setup procedure.

Great accessory for polar aligning
21 December 2019  | 

Fitting was a bit complicated, as my mount was one of the newer types that also required the RA motor and drive belt to be removed, but once in place, it went back together fine. First night out setup was a breeze. Simply allow the iPolar software to recognise the sky in two RA positions after giving the software your lat/long and barometric pressure and temperature, and you're all set! After that, I was bang on the pole within 3 minutes of starting making mount adjustments. Simply put the cross perfectly on the circle and it's job done. After that, I was running 3min unguided subs on my Skyguider mount with pinpoint stars. Could easily have gone longer! I am now sold on electronic polar finding - no more sore neck looking through a polar scope or drift aligning! 5 stars from me.
